AND JOHN R. DE LAMAR,

PATENT OFFICE.

ORE-CONCENTRATOR.

SPECIFICATION forming part of Letters Patent No. 337,683, dated March 9, 1886.

Application filed August 31, 1885.

To all whom it may concern:

Be it known that 1, WILLIAM HOOPER, of Ticonderoga, in the county of Essex and State of New York, have invented certain new and useful Improvementsin Ore Concentrators, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part'of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation of one of my improved ore-concentrators. Fig. 2 is a sectional plan view of the same, parts being omitted and parts being broken away. Fig. 3 is a plan of the annular bar, the radial arms R, and the bars Q, the sleeve parts being broken away and the shaft A in section; and Fig. 4 is a central vertical section, the shaft A being omitted.

The object of this invention is to provide ore-concentrators constructed in such a manner as to separate automatically the floating values, tailings, middlings, and concentrates, and which shall be reliable in operation, preserving all the metal.

The invention consists in the construction and combination of various parts of the oreconcentrator, as will be hereinafter fully described, and then pointed out in the claims.

A represents a vertical shaft, the upper part of which revolves in hearings in the frame B of the machine, orof the building in which the said machine is placed. The lower end ofthe shaft A revolves in a step, 0, secured to the floor of the building,the frame of the machine, or other suitable support.

Upon the lower part of the shaft A is placed aloose sleeve, D, to the lower end of which is attached a large beveled gear-wheel, E. The teeth of the beveled gear-wheel E mesh into the teeth of the beveled pinion-wheel F, attached to the inner end of the shaft G, which revolves in supports H, attached to the floor of the building, or to the frame of the machine. To the outer end of theshaft G is attached a fast pulley, I, and a loose pulley, J, to receive a driving-belt from any convenient power.

To an arm formed upon the upper end of 5o the sleeve D is attached a radial beam, K.

Serial No. 175,812. (No model.)

To the beam K are attached bearings, in which revolves a shaft L. To the inner end of the shaft L is attached a beveled pinionwheel, M, the teeth of which mesh into the teeth of the beveled gear-wheel N, attached to the shaft A. 5 To the outer end of the shaft L is attached a crankwhcel, O, to the crank-pin of which is pivoted the end of the connecting-rod P. The crank-wheel O is slotted radially to receive its crank-pin, so that the said crank-pin can be readily adjusted to give a longer or shorter throw to the crank, as may be required. The other end of the connecting-rod Pis pivoted to a support attached to or formed upon a ra dial bar, Q, the innereud of which is attached to an arm, R, formed upon the lower end of the sleeve S, placed upon the shaft A. Eight (more or less) radial bars, Q, may be used, which are placed at equal distances from each other, are attached at theirinner ends to arms 7c R of the sleeve S, and attached at their outer ends to an annular bar, T.

To the annular bar T are hinged, at a little distance from their outer ends, the radial bars U. The inner ends of the radial bars U are hinged to a sleeve, V, sliding up and down upon the upper part of the sleeve S, and carried around by and with the said sleeve S in its revolution.

Upon the upper part of the sleeveVis swiv- 8o eled a ring, \V, to the opposite sides of which are pivoted the lower ends of the rods X. The rods Xpass upat the opposite sides ofthe shaft A, and are pivoted at their upper ends to the forked end of the lever Y, which is fulcrumed to the lower end of the hanger Z. The upper end of the hanger Z is attached to the frame B. The outer endof the lever Y is perforated to receive the pin a, which passes through it and through one of a series of perforations in go a bar, b, pivoted at its upper end to the frame B, so that the lever Y can be secured in any position into which it may beadjusted. With this constructiomby operating the lever Y the sleeve V and the inner ends of the bars U,and 5 with them the inner ends of the sluices a, can be raised and lowered to give any desired inclination to the said sluices. The sluices c are secured to the hinged radial bars U, are placed side by side, and are widened toward rco their outer ends, so as to form an annular-I the heavier particles of rock, and known as 60 series of sluices.

d is the stirring-tub, which is supported by bars e,attached to the frame of the machine,or to some other suitable support. The pulverized ore and water are introduced into the stirring-tub d through aspout, f, and arekept mixed by an agitator, 9, attached to the lower end of a vertical shaft, h, the upper part of which isjournaled in the frame B. To the upper end of the shaft h is attached a pulley, i, to receive a driving-belt, which also passes around a pulley, j, attached to the upper end of the vertical shaft A, so that the said agitator will be driven from the said vertical shaft. The vertical shaft A is also provided with a pulley, 7a, to receive a driving-belt from any convenient power. The ore and water from the stirring-tub descape through faucets Z into the spouts m, by which they are conducted into the head ends of the sluices c. The spouts m are supported from the frame B' by rods n, as shown in Fig. 1. Beneath the lower ends of the sluices c is placed a circular trough, o,

ter is introduced into them from a perforated pipe, to, connected w1th a supply-pipe, w, and suspended from the frame B by rods 3 With this construction the revolution of the shaft G will carry the sleeve D and beam K around the vertical shaft A, and the; said beam K, by means of the shaft L and connecting bar P, will draw bars Q, U, sleeves'S V, and sluices o with it around the said vertical shaft A, so that the said sluices will successively receive ore and water, and at the same time the revolution of the vertical shaft A, by

' sluices.

means of the gear-wheels M N, will rotate the shaft L, and thus cause the crank-Wheel O and connecting-rod P to vibrate the bars Q U, sleeves S V, and sluices a, and thus facilitate the passage of the material down the said As theore and waterenter the sluices cthe lightest particles of metal, which are known as floating values, -fiow off with the water and are received in the section p of the trough'o, the pulverized rock, which is known as tailin'gs, and is the next lightest part of the material, is receivedin the section q of thetrough o. The lighter particles of metal and iniddlin'g's, are received in the third section, 1', of the trough o, and the concentrates, being the heaviest part of the material, are received in the fourth section, 8. The contents of the several sections are subsequently treated in the usual manner.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In an ore-concentrator, the combination, with a frame, of an annular series of radial sluices adapted to revolve in a horizontal plane and movably connected to said frame, and mechanism for imparting a vibratory movement to said sluices independent of their rotary' movement, substantially as set forth.

2. In an ore concentratonthe combination,

with a frame adapted for revolution ina horizontal plane, of a series of annnl'arly-arranged.

radial sluices, mechanism for raising and loweri-ng theinner ends of said s1 aims, and mechannular series of radial fla'ring slui-c'esadapted" -to have a rotary movement,- substantially as herein shown and described,whereby the head" ends of the said sluices will be broughtsu'ccessivel y beneath the feed an 1 the water" supply, as set forth.

4. In an ore-concentrator, the'combina'tion,

with the vertical shaft A, its driving mechanism, the rotating sl'eeveD', itsdri'vi ng mechanism, the sleeve S, radial arms and bars R Q,

and annular bars T, carrying the annular series of sluices c, of the beam K, attached to the said sleeve, the shaft L, journaled to the said beam, the gear-wheels M N, connecting as set forth.

5. In an ore-concentrator, the combination,- with the vertical shaft A, the siee've S; the radial arms and barsR Q, connected with the said sleeve, the annular bar T, connecting the bars U, the ring W, connecting-rods X, and

lever Y, substantially as herein shown and described, whereby the inclination of the said sluices can be readily regulated, as set forth.
